Getting Started
After you unpack and learn the layout and general operation of the Product, it can be set
up for operation.
Follow the subsequent steps to set up the Product:
1. Before you connect the power cord to the rear connector, make sure that the line
voltage selector is in the correct position for your location. The Product is shipped
from the factory with the line voltage set for the country of purchase. To make sure
the line voltage is correctly set, examine the indicator on the power line voltage
selector and fuse compartment cover.
2. See Table 3 to set the correct line voltage.
Table 3. Line Voltage Settings
Line Voltage (50/60Hz) Selector Position
100 V ac to 120 V ac 120 V ac position
220 V ac to 240 V ac 240 V ac position
3. If the line voltage is not correctly set, follow the instructions in “Changing the Line
Voltage” in Chapter 7 of the Users Manual.
4. When the line voltage is correctly set, make sure that the power switch is off and
connect the ac power cord to the Product. See the “Rear Panel” section of this
manual.
